UNITED STATES CHARLES H. NEVVHALL AND MILES PATENT OEEICE.

H. RAY, OF PROVIDENCE, RHODE ISLAND.

SPECIFICATION formingpart of Letters Patent No. 613,593, dated November1, 1898.

Application filed October 30, 1897.

To all whom t may concern:

Be it known that we, CHARLES H. NEWHALL and MILES H. RAY, citizens ofthe United States, residing at Providence,in the county of Providenceand State of Rhode Island, have invented a new and usefulCoin-Controlled Tire-Inater, of which the followingis a speciiication.

Our invention relates to slot-machines, and more particularly to amachine to be actuated by the dropping of a penny or other coin in aslot to open a valve to admit air under pressure to pneumatic tires.

The object of our invention is to furnish to bicycle dealers and othersa machine which without attention may be used to inflate the pneumatictires of bicycles and like vehicles by the rider thereof, the machinebeing actuated to open the valve by the dropping of a penny or othercoin into the slot.

Vith this object in View our'invention consists in a reservoir for thereception and holding of a supply of air under pressure, a pipe leadingtherefrom to a valve-cylinder incloscd within a casing, mechanism alsoinclosed within the casing whereby a coin dropped into the slot in thecasing becomes substantially part of the plunger by which the valve isopened, and an outlet from the valve-casing provided with means forattachment to the valve of the tire.

Our invention further consists in the improved construction,arrangement, and combination of parts hereinafter fully described andafterward specifically pointed out in the appended claims.

In order to enable others skilled in the art` to which our inventionmost nearly appertains to make and use the same, we will now proceed todescribe its construction and operation, reference being had to theaccompanying drawings, forming part -of this speciiication, in which-Figure l is a View in elevation, illustrating an intiating outfitequipped with our improvements. Fig. 2 is a sectional View, on anenlarged scale, of the valve and its operating mechanism. Fig. 3 is adetail view in elevation, on an enlarged scale, of the valve-operatingmechanism. Fig. 4 is a detail perspective view of the coin-operatingmechanism.

Serial No. 656,928. (No model.)

Fig. 5 is a vertical sectional view through the coin-operatingmechanism. Fig. 6 is a transverse section through the same.

Like letters of reference mark the same parts wherever they occur in thevarious figures of the drawings.

Referring to the drawings by letters, A is a reservoir of any approvedconstruction to receive and store air under pressure from any suitablesource, such as an automatic airpump, a delivery-pipe A2 also leadingfrom said reservoir, the reservoir being furnished, if desired, with apressure-gage of any ordinary construction to indicate the pressure ofthe air Within. The delivery-pipe A2 leads from an opening B, through abox or casing B, into a valve-cylinder O, and from such valve-cylinderprojects a delivery-pipe D, which may be provided with a suitable nozzleA3 to connect it with the tire A4 to be iniiated.

A slot E through the top of the box B leads to a channel between platesF and Gr, the latter of which rests against the side of the box or maybe the side of the box itself, the former being secured thereto byscrews H, the plates being a sufficient distance apart to permit acoin-as, for instance, a pennyto pass through the slot and down betweenthe plates into a position to rest in the rear of two springs I, securedby two of thev securing-screws F.

Extending from the plates F and G are rods or bars K and K', connectedby short iiat links L at their outer ends, leaving a space between thelinks L for the passage of a plunger M, which projects outside of oneend of the casing and is provided with a pushbutton N.

A spring O, coiled around the plunger and bearing at one end against theplates F and G and at the other end against a pin P, serves to hold theplunger normally in its outer position, it being prevented from beingpushed too far out by the pin P engaging the links L.

A coin-passage leads laterally from the point at which the penny engagesbehind the springs in line with the plunger M, so that when a penny hasbeen deposited and has dropped to said position of rest behind thesprings pressure inward upon the plunger M will push the coin along inadvance of it through said coin-channel and against the head R of avalve-stem R, carrying a valve S, which engages a valve-seat S in adiaphragm centrally located in the valve-cylinder C between the airinlet and outlet, and is normally held closed by a spring T. The valvehaving been opened by the inward pressure of the coin, air is permittedto pass through the valve-cylinder and the pipe D into the tire and willcontinue to pass into the tire until :it is fully inflated, when byreleasing the pressure on the plunger Mit will be thrown by the spring Ointo its normal outer position, which will leave the penny free to bepushed back in the coin-channel by means of the valve-stem impelled by aspring T, as before stated. Independent of this, however, thecoin-passage is inclined and the coin would usually roll back withoutsuch pressure.` When the coin reaches the ends of the springs I, it willnot pass behind them into its old position for the reason that theirends bear tightly against the inner plate G, but it will roll over theoutside of the springs and drop into the box or casing, there to remainuntil removed by a properlyauthorized person. The pressure of air in thereservoir will always be maintained by the automatic air-pump beforereferred to, but not shown.

While we have illustrated and described the best means now known to usfor carrying out our invention, we do not wish to be understood asrestricting ourselves to the exact details of construction shown anddescribed, but hold that any slight changes or variations, such as mightsuggest themselves to the ordinary mechanic, would properly fall withinthe limit and scope of our invention.

IIaving thus fully described our invention, what we claim as new, anddesire to secure by Letters Patent of the United States, is-

l. The combination with the box or casing, of the Valvecylinder,provided with a central diaphragm forming a valve-seat, an in let-pipecommunicating with one section and an exit-pipe communicating with theother section of the valve-casing at opposite sides of the centraldiaphragm, a spring-impelled valve-stem, carrying a valve to engage inthe valve-seat, and a coin-controlled mechanism whereby the valve-stemis pressed inward to release the valve, substantially as described.

2. The combination of the valve-casing, its valve and valve-stem, itsinlet and outlet pipes, with the coin-controlled mechanism provided witha slot in which to drop a coin, a plunger in line with the coin whendropped into the slot, and a spring for holding the coin in line withthe plunger, substantially as described.

3. The combination in a coin-controlled a pparatus, of two plates havinga coin-slot and coin-passage between them at an angle to each other,springs located at the junction of the coin-slot and coin-passageadapted to hold the coin dropped into the slot, their outer ends bearingagainst the inner plate beyond the coin, a spring-retracted plunger inline with the coin, a valve-casing, and a valvestem projecting from thevalve-casing in line with the plunger and coin, substantially asdescribed.
